CVE-2024-13419 in Smart Framework Plugin
Summary
by MITRE • 05/02/2025
Multiple plugins and/or themes for WordPress using Smart Framework are vulnerable to Stored Cross-Site Scripting due to a missing capability check on the saveOptions() and importThemeOptions() functions in various versions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugin's settings which includes custom JavaScript that is enabled site-wide. This issue was escalated to Envato over two months from the date of this disclosure and the issue is still vulnerable.

The vulnerability identified as CVE-2024-13419 represents a critical stored cross-site scripting flaw within WordPress plugins and themes that utilize the Smart Framework. This security weakness stems from inadequate access control mechanisms within the framework's core functions, specifically affecting the saveOptions() and importThemeOptions() methods. The vulnerability is particularly concerning because it allows authenticated attackers who possess at least subscriber-level privileges to execute malicious JavaScript code across the entire website. This flaw demonstrates a fundamental failure in the principle of least privilege, where the framework fails to properly validate user capabilities before permitting sensitive configuration modifications. The issue affects multiple plugins and themes simultaneously, indicating a systemic problem within the Smart Framework architecture rather than isolated component failures.
The technical exploitation of this vulnerability occurs through the manipulation of WordPress plugin settings where attackers can inject malicious JavaScript code that gets stored in the database and subsequently executed whenever the affected pages are loaded. This stored XSS vector enables attackers to perform a wide range of malicious activities including session hijacking, defacement, data exfiltration, and the deployment of additional malware. The vulnerability's persistence stems from the fact that the injected scripts are saved server-side and executed in the context of legitimate users' browsers, making detection and prevention particularly challenging. The attack requires minimal privileges since subscribers can exploit this flaw, which significantly increases the attack surface and potential impact. This issue aligns with CWE-79, which specifically addresses cross-site scripting vulnerabilities, and represents a clear violation of the security principle that privileged operations should be restricted to authorized users only.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with a persistent foothold within the WordPress environment. Once exploited, the malicious JavaScript can be used to modify website content, steal administrator credentials, redirect users to malicious sites, or even establish backdoors for continued access. The vulnerability's escalation to Envato over two months without resolution indicates a serious gap in the security maintenance process for popular WordPress frameworks. This delay in addressing the issue exposes countless websites to potential compromise, as the Smart Framework is widely used across the WordPress ecosystem. The persistent nature of the vulnerability makes it particularly dangerous for organizations that rely on WordPress for critical operations, as attackers can maintain long-term access and cause progressive damage to website integrity and user trust.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. Organizations should immediately update all affected plugins and themes to versions that properly implement capability checks before allowing configuration modifications. The implementation of proper access control validation in the saveOptions() and importThemeOptions() functions is essential to prevent unauthorized modifications. Security measures should include input sanitization and output encoding to neutralize malicious scripts before they are stored or displayed. Additionally, administrators should implement role-based access controls to limit the capabilities of lower-privilege users and consider implementing web application firewalls to detect and block suspicious parameter modifications. The vulnerability highlights the importance of regular security audits and prompt patch management processes, as well as the need for developers to follow secure coding practices that include proper capability validation and input validation. Organizations should also consider implementing monitoring solutions that can detect unauthorized configuration changes and alert administrators to potential exploitation attempts. This vulnerability serves as a reminder of the critical importance of maintaining up-to-date security practices and the dangers of relying on frameworks that do not properly enforce access controls for sensitive operations.
